You could pipe grep to "head -1" - might even improve the speed :-)

From your description, this sounds like stair-stepping. That's just CR/LF translation - you are sending a Unix file with only NL (LF) to a printer that wants CR/NL.

Most printers can be set to...

#!/bin/bash
read foo junk
echo $foo
echo $junk


$ ./t foo junk rest

foo junk rest
foo
junk rest

Or:

#!/bin/bash
read foo
set $foo
echo $1 $2 $3 etc.

./t foo junk rest more

Generally you'd use sed or awk to strip whatever you don't want. Something like

yourprog | sed 's/.* in//'

or

yourprog | sed 's/.* in/This is: /'

You mean you want me to write your script?

I gave three examples at that article. In comments people gave other examples. I think that's enough, but maybe not for you.

I'll tell you what: ...

You are mixing shell script commands into an FTP session. That doesn't work.

If you want more power from FTP, consider using Perl. See my Perl Net::FTP...

True, but the question is why would you do such a thing?

The answer is usually portability. If your script needs to ">file", that alone won't work everywhere and neither will "echo -n > file"...

You HAVE it in an array:

my @array_of_data = <DATA>;


So don't

print MAIL <DATA>;

do

print MAIL @array_of_data ;

I could be wrong, but that sounds a lot more like homework than a task delegated by a boss.

If you have shared memory, why does the server need to handle the input?

The client process writes and reads shared memory. What else is needed?

I'll second the nomination for Wordpress. I don't use it on my site because I'm a total control freak and don't like Php, but it really is the easiest way to get started and has enough legs to take...

If they are always named "xy_" something, then

cp `ls -ut xy_* | head -1` b/

works. Or if it's always 2 character underscore and date, then

cp `ls -ut ??_* | head -1` b/

If you are able to run it and someone else cannot, it's either perms (including perms on directories they'd need to traverse) or their PATH is not the same as yours.

Actually what you probably want is echo -e "First Line \n Second Line"

The answer is always always the same: something not set in ENV.

If you think it really is cron, see Cron is not working (http://aplawrence.com/Unixart/crontab_not_running.html)

Otherwise, a...

mt status

?
Solaris - mt (1) (http://www.smccd.net/accounts/sinkewitsch/msink/usail/man/solaris/mt.1.html)

There is so much left out here. What Unix? You might be running a modern Linux, Solaris, some old SCO system or who knows what and the issues of sending mail are going to vary with those.

What...

I'd strongly recommend using GNU grep. If that's simply not possible, see How can I recursively grep through sub-directories? (http://aplawrence.com/Unixart/recursivegrep.html)

$PPID contains the parent PID.

ps -p $PPID -o "comm="


gives you the calling process name and path.

Or single user mode (init state 1)

The problem isn't that it's mounted; it's that you don't want any other process writing to the fs while fsck is running.

As noted, the command could be made setuid (assuming its not a shell script). If your system has "sudo", specific users can execute specific or general commands as another user or as root. If...

Nowadays, I tend to use Perl. If it is very, very simple I might use a .netrc script but that gives no easy way to trap errors.

Kermit has good scripting for FTP too - I just tend toward Perl...

I might suggest that you approach this differently.

If the user is logged out, there will be no tty listed in ps - it will be a question mark.

Secondly - hanging processes like this are almost...

Something like this will do the csv part. You'll need a loop around your files and this code assumes one record per file - easy enough to change if that's not true

#!/usr/bin/perl
open(I, "t");...

Like i need to pass simple ls -ltrh >temp1 on a application server in mount point eg - /onestmp
how do i pass and capture the command.

How you pass the command depends on your programming...
